How should I, as founder, actually respond publicly when the brand is getting called out, what tone works vs backfires?

Defensive and legalistic responses are what actually escalate a crisis, brands and founders that survive viral callouts drop the corporate voice, use plain empathetic language, and take visible responsibility even when the full picture is still unclear, while ones that get pilloried further tend to sound staged, evasive, or combative. A founder personally responding can work brilliantly (it reads as accountability) or backfire badly (it reads as defensiveness) depending entirely on whether the tone is 'I'm sorry, here's what we're doing' versus 'you're wrong, here's why.' If you're not sure which way your instinct will land, have someone else read your draft before you post it, anger doesn't read the way you think it does from outside your own head.
